Attachment for rockers of chairs.

ATTACHMENT FOR ROCKERS OF CHAIRS.

Application filed June 11. 1913.

To all QUIZ/0777, it may concern:

Be it known that I, LAWRENCE L. WEI- SHAAR, a citizen of United States, residing at Erie, in the county of Erie, State of Pennsylvania, have invented certain new and useful Improvements in Attachments for Rockers of Chairs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention is directed to improvements in attachments for rockers of chairs, and has for its object to so construct an attachment of this nature that the same can be easily and quickly applied to the rockers of a chair, and held firmly in place thereon.

A further object of the invention is to provide an attachment of this nature which when in place provides a cushion for the chair so that the same when rocked will be noiseless and the danger of scratching the floor will be eliminated.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a side elevation of a rocking chair showing the attachment in place thereon.

Fig. 2 is a perspective view of the attachment removed.

Fig. 3 is a sectional View on line 3-3 of Fig. 1.

Referring to the drawing, the numeral 1 designates a chair having rockers 2, which are formed with longitudinal grooves 3, the same being concaved in cross section.

Specification of Letters Patent.

Patented July 10, 1917.

Serial No. 773,055.

The attachment comprises pneumatic tubes 4, to the opposite ends of which are secured metallic shoes 5, said shoes being provided with sockets 6 which are adapted to engage the ends of the rockers 2 so that the tubes 4: will engage the grooves 8.

The tubes i are provided with valves 7, so that the same can be inflated or deflated, said valves being of any well known construction.

In applying the attachment the tubes 4- are deflated and placed in the grooves 3 of the rockers, and while in their deflated conditions, the shoes will engage over the ends of the rockers, after which the tubes are inflated, thereby causing the shoes to tightly engage the ends of the rockers so as to pre vent accidental displacement of the rockers.

What is claimed is The combination with a rocker having a longitudinal groove formed in its bearing face, of a pneumatic tube adapted to lie within the groove and extend below the lower face of the rocker, a pair of shoe members adapted to fit over the ends of the rocker and having attachment lips to which the ends of the tube are connected, the latter being interposed between the upper faces of the lips and the bearing face of the rocker, whereby inflation of the tube tends to firmly seat the tube upon the rocker and draw the shoes into position.

In testimony whereof, I afiix my signature, in the presence of two witnesses.
